Supplemental oxygen is not always indicated for acutely ill patients and may contribute to mortality, according to new recommendations published recently in the BMJ.As part of the "Rapid Recommendations" initiative of the BMJ, a panel of experts — including specialists, a nurse, a surgeon, a respiratory therapist, and patients — evaluated a recent systematic review and meta-analysis and developed recommendations regarding supplemental oxygen therapy.The recommendations are aimed at treating critically ill patients, surgical patients with sepsis, hospitalized patients, or those en route to hospital in an ambulance. Postoperative, obstetric, and pediatric patients were not included in the review.Key recommendations include:-• Maintaining peripheral capillary oxygen saturation (SpO2) at or below 96% for patients receiving supplemental oxygen therapy• For patients with acute myocardial infarction or stroke, oxygen should not be administered if the initial SpO2 is ≥ 92%• Based on the available evidence, the panel made a weak recommendation against initiating oxygen therapy in those patients with an SpO2 between 90% and 92%Read more here: https://pxmd.co/V6e05Original guidance document can be read here: https://www.bmj.com/content/bmj/363/bmj.k4169.full.pdf
